President Obama’s support among Catholic voters has surged since June, according to a new poll, despite a summer that included the Catholic bishops’ religious freedom campaign and the naming of Rep. Paul Ryan, a Catholic, as the GOP’s vice-presidential candidate.
On June 17, Obama held a slight edge over Mitt Romney among Catholics (49-47 percent), according to the Pew Research Center. Since then, Obama has surged ahead, and now leads 54-39 percent, according to a Pew poll conducted on Sept. 16.
Among all registered voters, Obama leads Romney 51-42 percent, according to Pew.
Obama and Romney are essentially tied among white Catholics, which some pollsters call the ultimate swing group.
On Monday (Sept. 24) Romney unveiled his Catholics for Romney Coalition, which includes numerous politicians, beer magnate Pete Coors and Princeton University intellectual Robert P. George. The Obama campaign also has a Catholic coalition.
